To all whom t may concern.'

Be it known that we, HENRY: A. RUETER and EnAsTUs E. VINKLEY, citizens of the United States, residing at Jamaica` Plain, Boston, Massachusetts, and Lynn, in the county of Essex and Commonwealth of Massachusetts, have 'invented certain new and useful Improvements in Machines for Vash-` ing Tumblers,V and. we hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled inthe art to which -it appertains to make and use the same.

The invention relates to an improvement in machines for washing tumblers and articles of a likenature. Y 1

The object of the inventionis toproduce a washing machine of such construction that the operation of automatically washing. or cleaning tumblers and articles of a like nature may be performed `more thoroughly and expeditiously than has hitherto been possible with the machines now in use. Tor the accomplishment of this object, the in-I vention consists in the improved tumbler washing machine hereinafter described and particularly pointed out in the appended claims.

The preferred form of the invention vis illustrated in the accompanying drawings,

in vwhich Figure lis a sectional viewv taken on the line l-l of Fig. 6; Fig. 2 is a sectional detail of one of the valves; Fig. 3 is a sectional view taken on the `line 8-3 ofFig. 6; Fig. a is a sectional View taken on the line 4 4 of Fig. 6; Fig. 45 is a section, on an enlarged scale, taken on the line 5-5 of Fig. l; Fig. 6 is a top plan of the machine with the cover removed; Fig. V7 is a sectional view taken on the line 7-7 of Fig. 3; Fig.` 8 is a partial sectional view, `similar" toFig. 1, showing the mechanism of the left-hand part of the machine in a different position; Fig.- 9 is a sectional view taken on about the line 9-9 of Fig. 3; Fig. 10 is a section taken on the line 10-10 of Fig. 7; and Fig. 11 is a top plan of themachine on a reduced scale. A A f The tumbler washing machine illustrated in the vdrawings consists essentially of two rolls rotating at different speeds, `one roll being adapted to support the tumbler during theA washing operation and to press it against the othernroll-the tumbler being inserted upside down on the lirst named roll;A The difference in the speed `of rotation between the two rolls causes the tumbler to be moved relatively to both rolls, and this movement results `in the washing ofthe sides of the tumbler, means being provided for washing the inside and outside of the bottom. In the machine 'illustrated in the drawings there are` two tumbler supporting rolls,

which may be brought into operation separately for simultaneously for pressing two tumblers against the roll for washing the outside ofthe tumblers. This duplication of the Vtumbler supporting roll is made merely forthe sake of facilitating the washingof a greater number of tumblers, and is not essential to the operation of the machine, one tumbler supporting roll working equally as well as two tumbler supporting rolls in coperation with the outside wash-v ing roll. y Y

\ Theroll for washing the outside of the tumblers is centrally disposed in the machine, and consistsof a number of layers of rubber l5, or like material, which are secured to the periphery of a cylindrical core 1G screwed on the upper endof-a vertically arranged shaft 17 suqoportedV at its bottom end by a `boss 18 rising froma webY 19 forming a portion of the "frameof the machine. Loosely surrounding the lower end of the shaft 17 is a sleeve 21 supported in a lowerVV bearing Q2 and in an upper bearing 23. The lower bearing22 projects upwardly fromj a web 24, which extends across the whole of the machine andprotects the mechanism which actuates the rolls from the water employed for cleaning the tumblers. The upper bearing 23 is connected withthe web Qtand with the upper portion 25 of the frame of thel machine. Secured to the lower part of the sleeve 21 is` aA vworm gear` 26 `which meshes with a worm 27 secured tothe shaft 28 of a motor QQ'supported in a housing 30 located outside the frame off the machine. The motor shaft 28 is journaled in a bearing 32; and

fastened von the lower end ofthe shaft 17.v Below the pinion 40 is a pinion 42 also fastened to the sleeve 37, and which meshes with a gear 43 secured to the upper portion of a cam shaft 44 journaled in the boX.

frame 39. On the shaft 44 are secured an upper ratchet disk 46 and a lower ratchet disk 47, and located above the ratchet disks 46 and 47 are cam disks'48 and 49 respectively, which loosely embrace, the shaft 44. By reason o'f this arrangement, the ratchet disks are normally in constant rotation, while the cam disks remain normally stationary. The purpose and function of these disks will be presently explained. The upper end of the vertically disposed shaft 17 is provided with an oil hole 51, by which the bearing surfaces between the sleeve 21 and the shaft 17, and the bearing surfaces between the sleeve 21 and its bearings, may be lubricated. The lubricant is contained in the cup 52 screwed in the upper end of the shaft 17. A cap 53 closes the upper end of the cylindrical core 16; and an inverted cupshaped disk 54 serves to prevent water from getting into the bearing surfaces beneath it.

The tumbler' supporting'rolls, which are indicated generally at 56 and 57, are best seen in their relative positions with respect to the central roll in Fig. 1. The righthand roll is shown in the act of washing a tumbler 58, and the left-hand roll is shown in its normal position, a tumbler 59 having been placed upon it. Each tumbler supporting roll consists of a cylindrical outer portion 60 composed olf rubber or like yielding material, which is secured to a cylindrical core 61. The core 61 is fastened to the upper end of. a sleeve 62 which loosely embraces, for sliding purposes, the upper end of a shaft 63 journaled in a sleeve 64 which rises from the middle portion of a yoke 65 provided at each end with downwardly depending lugs 66, which are received between upwardly extending bosses 67 rising from the upper surface of the web 24. The upper end of the shaft 63 is provided with a driving head 69, (best seen in Fig. 5), which is adapted to slide in a slot 70 cut in the upper end of the sleeve 62. In this manner provision is made so that the shaft 63 may drive the roll 60, and the roll 60 may be moved longitudinally relatively to the shaft. A helical spring 72 surrounding the shaft 63, the upper end of the spring taking against a shoulder 73 on the sleeve 62, and the lower end of the spring taking against a roller bearing block 74, which is provided to eliminate friction, serves to normally maintain each tumbler supporting roll in the elevated position which the lefthand supporting roll 56 occupies in Fig. 1. Secured to the lower end of each shaft 63 is a gear 76 which meshes with a large pinion 77 secured to the sleeve 21. The gears 76 are in constant engagement with the pinion 77, whether the tumbler supporting rolls occupy their nor mal position, as shown by the position of the left-hand roll in Fig. 1, or whether they occupy their operative position, as shown by the position of the right-hand roll in Fig. 1. The upper end of each tumbler supporting roll is closed by a cap 75, on the top of which is secured arubber disk 78 for cleaning the inside of the bottom of the tumbler. It will be observed that by reason of the different sizesof the gears provided for driving the central roll and the tumbler supporting rolls, the two tumbler supporting rolls are driven at one speed and that the central roll is driven at a different speed.

The left-hand and right-hand tumbler supporting rolls are respectively provided with push rods 80 and 81. The push rod 8O is provided with an upper head 82 and a lower head 83. The push rod 81 is provided with an upper head 84 and a lower head 85. W'hen a tumber is inserted on each or both of the tumbler supporting rolls, as shown in Fig. 1, the operator presses down upon them until the lower heads of the push rods engage the heads 86 and 87 of the rods 88 and 89 respectively. These rods 88 and 89 are slidingly mounted in vertical holes in bosses at each side of the webv 19. Vhen a tumbler supporting roll has been pushed down as far as it will go, it occupies a position as shown by .the posi-tion of the left-hand tumber supporting roll in Fig. 8, the head of the push rod then being engaged and temporarily held by a catch 90 pivoted at 91. Each catch 9() is pressed toward its respective rod by means of a spring-pressed plunger 92, the stop 93 limiting the movement thereof. The lower ends of the rods 88 and 89 rest on the outer ends of levers 94 and 95 respectively. Each of these levers is provided with a wedge-shaped structure 96, upon which normally rests theouter end of a dog 97 pivoted to a lug 98 depending one each from the under surfaces of the cam disks 48 and 49. The ratchet disks 46 and 47 are provided with ratchet teeth 100, each of which has a vertical surface and an oblique surface, the vertical surfaces facing in the direction of rotation of the ratchet disks. lVhen a push rod has been moved into the position shown in Fig. 8, the consequent depression of one of the rods 88 or 89 oscillates either of the levers 94 or 95 so as thereby to swing the cam wedge 96 clear of the outer end of the d-og 97. Thereupon the dog descends under the action of gravity and is caught by one of the ratchet teeth 100, and the cam disk to which the dog is articulated is rotated yichronously with its respective ratchet The upper cam disk 48 is provided with an outer cam ysur-face 101 and an inner cam surface 102, andthe lower ca-m disk49 is provided with an outer cam surface 103 and an inner cam surface 104. The cam surfaces 101 and 103 consist of short segments, and the cam surfaces 102 and 104 comprise complete circles, and are provided with inactive depressed portions 105 and 106 respecj tively. The lower cam disk 49 is adapted for coperative action with the left-hand tumbler supporting roll, andthe upper cam disk 48 is adapted for coperative action with the right-hand tumbler supporting roll. The vcam surface 103 is normally engaged by a cam roll 108 carried on the outer end of thearm 109 of a bellcrank lever 110 pivoted on a stud 111 secured in the machine frame. The outer end of the other arm 1 12 of the bellcrank 110 engages the upper side of a. pin 113 passed through the lower end of a rod 114 slidinglymounted in an elongated boss 115 depending from the under side of the web 24. To .the upper end of the rod 114 is secured yan inverted cap 116 pivoted to the outer end of an arm 117 integral with the left-hand tumbler roll supporting yoke 65. A spring 119 tends to raise the rod 114. The constructionof the corresponding parts of the right-hand tumbler supporting roll is similar. s The outerpcam surface 101 of thevcam disk48 normally engages a cam roll 121 carried by the outer end of the arm 122 of a bellcrank lever 123 fulcrumed on the stud v124 secured in the machine frame. The other ar1n125 of the bellcrank 123 engages a ypin 126 passed through the lower end of a rod 127 slidingly mounted in a boss 1 28 depending from the web 24. To the upper end of the rod 127 is secured a cap 129 pivotedv to theV outer end of an arm 130 integral with `the right-hand tumber roll supporting yoke 65. A spring 131 tends to raise the rod 127. When the parts of the machine are in normal `or inactive position, the cam tsurfaces 101 and 103 respectively engage `the cam rolls 121 and 108, thereby causing the outer ends of their respective levers to vdepress the rods 114 and 127, against the action ofthe springs 119 and 131 respectively, so that the tumbler supporting rolls are held in the position of the left-hand tumbler supporting roll as shown in Fig. 1., But when tumblers have been inserted on the tumbler supporting rolls, and they have been pushed down until the rods 88 and 89 have been depressed suiiciently to oscillate the levers 94 and 95, thereby swinging the wedges 96clear of the dogs 97, whereby the `dogs are permitted to beengaged by the ratchetl teeth 100 of the ratchet disks, the cam disks are rotated and the cam surfaces 101 and 103 fare caused to pass from under the cam rolls 121 and 108 so that the springs 119 and 131 act t`o throw the tumbler supporting .rolls into the position occupied by the right-hand tumbler supporting roll in Fig. 1. This causes the outside of -the tumbler to be quite firmly engaged by the central roll, and the inside of the tumbler to be quite firmly engaged by the tumbler supporting roll. The rubber, by reason of its yielding nature, as the rolls rotate at their different rates of speed, scours the surfaces of the tumbler, the slipping action of the tumbler relatively to the two rolls effectively causing the complete circumference of the inside and ou-tside of the tumblers to be engaged and therefore washed before the washing operation ceases. Immediately the tumbler supporting rolls assume their vertical operative position with relation Ito the central roll, the lower heads 83 and 85 of the push rods 80 and 81 respectively are disengaged from the catches 90, and the springs 132, which are connected with the levers 94 and 95, act to return the levers to their normal position, as shown at the right-hand part of Fig. 1. The wedges 96 are thereby returned to their norlmal position in the path of the outer ends of the dogs 97. Each wedge is provided with a wall 133 against which the end of the dogs 97 strike. The cam disks are thereby positively stopped ata definite point in their rotation. It is thus seen that during the washing operation of each tumbler, the cam disks perform only one revolution. The washing rolls, however, and perforce the tumblers, are rotated many times during the single revolution of the cam disks.

The rotation of the cam disks causes thc depressed portions 105 and 106 of the cam surfaces 102 and 104 respectively to pass from under the cam rolls 135 and 136 (Figs. 7 and 9), by which the cam surfaces 102 and 104 are respectively engaged. The cam roll 136 is carried by a stud secured in an arni 137 of a lever 138 pivoted on a stud 139 secured in the bosses projecting rearwardly from the box frame 39. Upon the free end of the arm 137 rests the lower end of a valve rod 140, the upper end of whichis slidingly received in a hole in the web 24. Secured to the upper end of the rod 140 is an inverted cap 141 to prevent water from reaching the lower part of the machine. The upper end of the rod 140 terminates immediately below the lower end of a valve stem 142 of a valve 143.

The cani roll 135 is fulcrumed on a stud 144 lixed in an arm 145 of a lever 146 fulcrumedy on a stud 147 fixed in bosses situated above the stud 139 at the rear of the box frame 39. Resting upon the outer end of the arm 145 is a valve rod 149, theup per end of which is slidingly received in a hole inthe web 24. An inverted cap 150 is secured to the rod 149, and prevents water from leaking down through the space between the rod 149 and its hole in the web 24. The upper end of the rod 149 terminatos below the lower end of a valve stem` 152 of a valve 153, the internal construction of which is shown in Fig. 2. The internal construction of the valve 143 is similar in all respects to the valve 153. Each valve stem is provided with a valvedisk 154 which is kept normally seated by a spring 155. 'When the active parts of the cam surfaces 102 and 101 come into engagement with their respective cam rolls, and thereby act to raise the valve rods 149 and 10 so that the upper ends of the valve rods are respectively brought into engagement with the valve stems 152 and 142, the valve disks 1511 are unscated, thereby permitting the water held in check to pass into the tubes 157 and 158 respectively. These tubes run toward the front of the machine, and terminate in upright pipes 159 and 160. Thesepipes direct j ets of water on the outside of the tumblers through small apertures 161. Branching from each side of the tubes 157 and v158 are four heads 162, two from each tube respectively. These heads are provided with apertures 163 through which streams of water are squirted into the inside of the tumblers. The valves are joined by a pipe 161 and are supplied by a main 165. When the depressed portions 105 and 106 of the cam surfaces 102 and 101 respectively are again under theirV respective cam rolls, the valve springs 155 act to close the valves and push the valve rods down, thereby depressing the cam rolls into their respective depressions. These movements take place when the dogs 97 come into engagement with the stops 133 on the wedges 96.

When a tumbler has been inserted on a tumbler supporting roll, and it has been pushed down so that the push rod is caught by the catch 90, to permit the mechanism to come into `operation to slap the tumbler up against the side of the central roll, a swinging door is closed over the aperture through which the tumbler supporting roll is reached in order to prevent any water from squirting out of the machine. The top of the machine is provided with a cover 167, and in this cover are cut two apertures 168, each of which is located over a tumbler supporting roll. rlhe aperture above the left` hand tumbler supporting roll is adapted to be closed by the door 169, and the aperture above the right-hand tumbler supporting roll is adapted to be closed by the door 170.

The doors 169 and 170 are respectively pivoted on the studs 171 and 172 fixed in a rib 173. The outer free ends of the doors slide in grooves 174 formed in the inner edges of a shelf 175, projecting inwardly from the frame of the machine. The door 169 is swung into open position by a cam boss 177 (Fig. 7) formed on the peripheral edge of the lower cam disk 49, and for this purpose the cam boss 177V is adapted te engage a'cam roll carried bythe outer end of an arm 179 secured to the lower end of a vertically disposed rod 180 which is journaled in the rear part of the frame of the machine. The upper end of the rod 180 passes through the shelf 175, and to it is secured an arm 181, toA the outer end of which is pivoted one end of a link 182, the other endof the link 182 being pivoted to anarm 183 which is in xed'relation with the door 169. When the cam boss 177 is disengaged from the roll 178, due to the rotation of the cam disk, the spring 185, acting through the connections betweentlie arm 181 and the door 169, swings the door 169 on its pivot 171 and thereby closes the opening above the left-hand tumbler supporting roll. Upon the completion of one rotation of the'y cam disk 49, the cam boss 177 again engages the cam roll 178, thereby forcing the arm 179 outwardly, and with it the arm 181. The outward movement of the arm 181 acting upon the arm 183swings the door 169 into open position, as'shown in Fig. 6. The construction of the operating means for the door`170 is similar in all re spects to the construction of the operating means for the door 169. The door 170 is normally held in open position by a cam boss 187 formed on theY periphery of the cam disk 218. In holding the door 170 open, the cam boss187 engages the cam roll 188 carried on the outer end of an arm 189 Vsecured to the lower en'd of a rod 190; The upper end o'f-therod 190'projects through the shelf 175, and to it is'secur'ed an'arm 191, on the outer-end ofiwhich is pivoted one end of a link `192, theother end of the linkbeing' pivotedto 4an arm 193which has a fixed relation to the door 170. Vhen the cam disk 48 rotates, and thereby disengages the boss 178 from the roll 188, a spring 195 acts to close the door 17 0. When the cani boss187 again comes into engagement with the roll 188, the vdoor 17 0 is swung into open position. On the "under side of each door is secured a piece ofresilient material, like rubber, which is indicated at 196. This piece 196 is so locate'dthat when the-doors are shut, it comes into contact with the out side of the bottom of thetumbler and there by cleans it yas the tumlbler'rotates.

Means are `pro-vided for removing the surplus waterfr'om the surfaces of the tumbler. These-means are'lbrought' into action during the tumbler washing operation, and comprise an inside wiper and an outside wiper. There are two insidewipers and two outside wipers. Each inside wiper 197 is pivoted at 199 on the upperend cfa lever 200 fulcrumed'at 201 on an upright 202'rising from the upper surface of Y the web v24. The tumbler wiping portion of tlhe wipers is composed of rubber or some other resilient water-resisting material which is Secured to a frame 203. The wipers are pivoted so that they may be self-adjusting toconform tothe inside surface of the sides of the tumJbler when in active position. When the tumbler supporting Vrolls yare in normal or inactive position, the inner edge of the upper part of the wipers is held in close; proximity with the outer surface of the tumbler supporting roll, as shown at the left-hand side of Fig. 1, and also in Fig. 8. This is for the purpose of enabling the operator to easily insert the tumbler over both the tumbler supporting roll and the wiper. When the tumbler is in the Vposition it occupies during the washing operation lthe tumbler engaging edge 205 of the insidewipers is brought into engagement with the inside of the tumbler, as shown in the right-hand section of Fig. 1. The means for holding the inside w-iper against the tumbler supporting roll while the latter is in inoperative position` comprises pins 207 fixed in the sides of the caps 116 and 129.n These pins 207 engage the inturned lower ends of the levers 200 while the cam surfaceslOl and 103 are in engagement with rtheir respective cam rolls carried by the levers which controlthe rods 114 and 127, upon the upper ends of which the caps 116 and 129 are fastened. When, owing to the rotation `of the cam disks 48 and 49, the cam surfaces 101 and 103 pass beyond their respective cam rolls, and the springs 119 and 131 are thereby permitted to raise the rods 114 and 127, and so the caps 116 and 129; the pins 207 are disengaged from the inturned lower ends of the levers 200, whereupon .the coiled spring 208, with which each. lever 200v is provided, Vis permitted to act upon its lever to swing its outer end outwardly into contact with the inner surface vof the sides of the tumbler, thereby removing anyV surplus water therefrom during the washing oper ation.

The outside wipers which remove the surplus water from the outside surfaces of the sides of the Vtumblers are, carried bythe doors `169 and 170. These outside wipers 210, which are composed ofthe same material as the inside wipers, are secured to a framework 211 having Van upper arm212 and a lower arm 213 which engage and are held in position by a stud 214 depending` from each door. A helical spring 215,.sur rounding the stud 214, acts to press the wiper toward the tumbler. When a tumbler has been placed vupon one ofthe supporting rolls, and the door has closed, thereby bringing a wiper 210 into engagement with the outside of the wallsV of the tumbler, the spring 215 acts to hold the wiper in yielding engagement therewith. Y

As the lwater is squirted onto the inside and outside of the tumblersduring the washing operation, it falls onto the upper surface of the web '24. This web slants from the center radially downwardly and outwardly toward the outside of the machine, where a trough is formed, as is clearly shown in Figs. 1 and 4. The front part of this trough is slightly lower than the rear, andnn each corner thereof is fixed a drain 217 which gives into a drainl pipe 218, by which the used water is conveyed away.

It has become apparent from the foregoing description that the left-hand and the right-hand tumbler supporting rolls may be used separately orY they may be used alternately or simultaneously in conjunction with the central roll, their actuating parts being so constructed as to permit this diversity of operation. As'already described, while the parts are in normal or inactive position the doors 169 and 170 are open, and the tumbler supporting rolls are in elevated position, as shown by the left-hand tumbler supporting roll in Fig. 1. The operator theninverts th'e tumbler to be cleaned and inserts it over the tumbler supporting roll and the inside wiper. The position of the tumbler at 4the moment of insertion is shown in Fig. 1. The tumbler is then pushed down until the push rod is caught by the catch 90. rlhe position of the parts of the mechanism at this time is shown in Fig.'8'. The depression of the push rods results in the oscillation of either the lever 94 or the lever 95, according to whether the left-hand or right-hand tumbler supporting roll is being brought into operation, and when either of these levers has been oscillated, thereby disengaging the wedgef96 from the dog 97, allowing the latter to `fall and be engaged by the ratchet teeth 100 of either the ratchet disk 46 or ratchet disk 47, the cam disk48 or the cam disk 49 is rotated synchronously with its corresponding ratchet disk. Therotation of the cam disk results in the vertical positioning of theytumbler supporting roll into the position occupied by the right-hand tumbler supporting roll, as shown in Fig. 1. While the tumbler supporting roll is coming into its vertical position, the cam boss formed on the outside of the cam disk passes `from en'- gagement with its respective cam roll, and the proper door is closed over the aperture in the cover of the machine. Substantially simultaneously with the attainment of vthe vertical position by the tumbler supporting roll and the closing of the door, the inner cam surface of the cam disk operates to open the valve controlled by it and allow water to be squirted Onto Vthe inside and outside of the tumbler. The closing of the doors brings the, outside wiper into contact with the outside `of :the walls of the tumbler, and the attainment of its Vertical position by the tumbler sup-porting roll brings the." inside wiper into contact with the inside of the walls of the tumbler. When the cam disk has performed one complete rotation, the depression in the inner cam surface of the cam disk is again opposite its respective cam roll, and the spring 155 in the valveacts to seat the valve disk, thereby shutting ofil the water; the cam boss again comes into engagement with its respective roll, and thereby opens the door to which it is connected, and the outer cam surface of the cam disk again passes under its respective cam roll, thereby depressing either the rod 114 or the rod 127, by which the tumbler supporting roll is returned to its normal oblique position. Thereupon, the catch 90 having previously released the lower head of the push rod when the roll attained its vertical position, the spring 72 acts to raise the roll andthe tumbler into the position shown Vfollowing claims.
